The shooting turned what had been a good-natured season-opening event for a league of passionate Madden football players into the latest scene of carnage resulting from a mass shooting in the US.

“It’s heartbreaking,” said esports journalist and consultant Rod “Slasher” Breslau. “It’s very hurtful to have these kinds of issues that we see everyday here as Americans, and now it’s coming directly home.”

The tournament, which was taking place at a bar in the Jacksonville Landing outdoor mall, was hosted by Electronic Arts, the publisher of the Madden video game franchise. The event was the first of four regional qualifiers for the Madden Championship event slated for later this year in Las Vegas. The event featured several professional players as well as dozens of aspiring esports players.

While esports has grown into a more than $500 million industry according to Goldman Sachs, the leagues based on real-world sports like football and basketball are generally considered smaller than the leagues for fantasy and first-person-shooter games such as Call of Duty and Dota 2.

But news of the tragedy quickly spread across the broader industry of video gamers and esports contestants. During a League of Legends tournament on Sunday, the video stream included a live statement to pay respects to the victims of the shooting in Florida.

According to the LA Times, the shooter was a participant in the Madden tournament who had been eliminated earlier in the day, but authorities did not provide a motive or confirm whether Katz was involved in the tournament.

EA did not return requests for comment, though it tweeted statements earlier that it was working with the authorities to gather facts about the “horrible” situation.

Focus is turning to security at eSports events

The rapid growth of esports have prompted concerns about security at gaming events.

According to Breslau, there have been occasions at some esports events when people have managed to get in front of the video cameras streaming the tournaments. Although those incidents involved people being crass or making jokes, they highlighted a lack of security within the fast-growing industry, Breslau said.

In 2015, two gamers were arrested after travelling from Iowa to a Pokemon tournament in Boston equipped with 12-gauge shotgun and an AR-15 assault rifle.

While the security at major esports events is generally on par with that of professional sporting events, that’s not usually case at the numerous smaller events like Sunday’s Madden qualifier, which took place in a bar.

The atmosphere at live gaming events can be intense, Breslau noted, especially when significant prize money is at stake. Trash talking among players is very common. But Breslau stressed that the overall experience is one of fun.

“We’re a community of gamers,” Breslau said, noting that he’s never witnessed a real-world physical fight at an event before.

And while the shooting occurred at a tournament for a football game, Breslau said he’s bracing for some people to try to blame video games for the violence.

“I know the gaming community will come out and be a positive force in the wake of everything that happened this weekend,” Breslau said, but “I do know that some people will try to make this about ‘Gamers are bad.'”
